    Forcing AD Replication in Windows Server 2008

    In previous versions of Windows (2000 & 2003) the following registry setting
    was used on DCs to force a "master" replication of the AD:

    HKLM\System\CurrentControlSet\Services\ntfrs\parameters\Backup/Restore\Process at Startup\Burflags = D4.

    This key, or anything similar, does not seem to be present in Windows Server
    2008 (a "burflags" search does not find anything).

    Is it possible to force AD replication in this new OS?

    Thanks

    D.

    Check Meinolf's reply. Note that this triggers an _authoritative_ restore of
    the SYSVOL folder. You should know what you are doing here. Also please not
    that this only handles SYSVOL replication - not the core AD database
    replication.

    Cheers,
    Florian

    RE: Forcing AD Replication in Windows Server 2008

    Thanks guys

    I have used this many times on 2000 and 2003 systems so I understand the
    process and I agree we are talking about SYSVOL replication.

    The problem is I don't have that key on my system. The only keys under
    HKEY_LOCAL_MACHINE\ SYSTEM\CurrentControlSet \Services\NtFrs are:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NtFrs\Parameters
    and
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NtFrs\Parameters\SysVol

    and even those are fairly empty of data

    SYSVOL is replicating OK and new Ad Objects can be created

    My DC is from a fresh install not a 2003 upgrade.

    Any ideas?

    RE: Forcing AD Replication in Windows Server 2008

    FYI: I have discovered this is a “domain functional level” issue.

    Domains operating at a functional level of 2000 and 2003 use File
    Replication Service to distribute the SYSVOL data around the DCs. The
    registry reflects this accordingly and the
    HKLM\System\CurrentControlSet\Services\ntfrs registry key contains the full
    complement of keys and data that I am familiar with.

    Domains operating at a functional level of 2008 uses Distributed File System
    Replication and so the registry features associated with 2000 and 2003
    functional levels are not present.

    However, I still need to know if it is possible to re-initialise File
    Replication on domains running at Windows 2008 functional level. I will keep
    working on it.
